Of course, this site is also created from reStructuredText sources using Sphinx! HTML (including Windows HTML Help), LaTeX (for printable PDF versions), ePub, Texinfo, manual pages, plain text. Semantic markup and automatic links for functions, classes, citations, glossary terms and similar pieces of information. Easy definition of a document tree, with automatic links to siblings, parents and children. General index as well as a language-specific module index. Automatic highlighting using the Pygments highlighter. Automatic testing of code snippets, the inclusion of docstrings from Python modules (API docs), and more. -

Swagger Editor
An editor designed for Swagger
Swagger Editor lets you edit Swagger API specifications in YAML inside your browser and to preview documentations in real time. Valid Swagger JSON descriptions can then be generated and used with the full Swagger tooling (code generation, documentation, etc). swagger-editor is a traditional npm module intended for use in single-page applications that are capable of resolving dependencies (via Webpack, Browserify, etc). swagger-editor-dist is a dependency-free module that includes everything you need to serve Swagger Editor in a server-side project, or a web project that can't resolve npm module dependencies. If you're building a single-page application, using swagger-editor is strongly recommended, since swagger-editor-dist is significantly larger. -

OpenAPI Generator
OpenAPI Generator allows generation of API client libraries
With 50+ client generators, you can easily generate code to interact with any server which exposes an OpenAPI document. Maintainers of APIs may also automatically generate and distribute clients as part of official SDKs. Each client supports different options and features, but all templates can be replaced with your own Mustache-based templates. Getting started with server development can be tough, especially if you're evaluating technologies. We can reduce the burden when you bring your own OpenAPI document. Some generators support Inversion of Control, allowing you to iterate on design via your OpenAPI document without worrying about blowing away your entire domain layer when you regenerate code. Ever wanted to iteratively design a MySQL database, but writing table declarations was too tedious? OpenAPI documents allow you to convert the metadata about your API into some other format. -

DocSearch
The easiest way to add search to your documentation
Initially created to fulfill our own developers' needs, DocSearch quickly evolved into a successful community project. Over the years, we've explored new ways to address the complexities of search for the open-source community.

With a design very close to the native experience on mobile, we leverage users acquaintance with the interaction patterns of each OS. We scrape your documentation or technical blog, configure the Algolia application and send you the snippet you'll have to integrate. It's that simple. You don't need to configure any settings or even have an Algolia account. We take care of this for you! We'll send you a small snippet to integrate DocSearch to your website and an invite to your fully configured Algolia application. -
